Abstract

Geogrid in pavement application is widely used today, as it mainly functions as soil reinforcement or as a separator. Geogrid is made up of polymers which makes it resistant to degradation. There are different kinds of polymers which are widely used today in a familiar term called plastics. For the past years, plastic aluminum laminates (PAL) and high-density polyethylene (HDPE) plastic bags were used as packaging materials or containers.  However, the use of these plastics generates a huge amount of waste, consuming a lot of space and damaging the natural state of the earth. This research aims to utilize these wastes to form geogrid, which will be applied in pavement design. The recycled plastics undergo the melting process, with the aid of the two-roll mill and the compression molding. Then apertures are carved into a grid-like structure. A total of nine mixtures of geogrids were produced, each mixture having a different composition of HDPE, PAL, and organoclay. Tensile test for geogrids by Multi-rib Tensile Method (ASTM 6637) and tensile test for plastics (ASTM D638) are followed to test the geogrids.  Based on the data obtained, it showed that higher tensile strength is achieved when the amount of HDPE composition in the material increases. In terms of the addition of organoclay, the mixture with 98% HDPE and 2% organoclay produced the highest tensile strength. The product of the study exhibiting the highest strength was classified as either class 2 or class 3 geogrid.
